Could violent video games reduce violent crime rates?

That's an interesting thought, but that's exactly what Patrick Kierkegaard from the University of Essex claims is the only logical conclusion one can make from comparing video game sales and violent crime rates objectively.

He's published a study that says there's no evidence to support the claims that violent video game playing causes violence. He says:

"With millions of sales of violent games, the world should be seeing an epidemic of violence. Instead, violence has declined."

He further claims research into the topic is inconclusive and many existing studies are biased in one way or another. There's need for more comprehensive research, he concludes.
